Well I will say this...
After running The Tail of the Dragon at Deals Gap, with 318 curves in 11 miles, my Intercooler was nice and cool like I have stated several times. Most of the Dragon is run in 2nd and 3rd gear at high RPMs for longer than normal lengths. The clutch is ONLY used to shift gears as you would drive in track events.
I honestly think it is safe to say that even on track day... you would have 0 issues with the charge temps.

I really need to buy on of those point n shoot ambient surface temp readers. I know when Cam and I were tuning. We pulled in the shop after 1 hour of rather dogged driving and the temps were 118 - 122 F anywhere on the Pettit system. Cool enogh you could lay your face on the intercooler with out worries. Well at least you could hold your hand there with no discomfort.

Go to bed Dan! J/K. I'm actually going to wait until the morning to install the H/U. I got the harness connected, but I'll finish cramming everything in in the morning. Thanks again!

heck on a 90 degree day in ga the top of my revi box is 124--top of my battery is in the 120's, top of my coils are 160(before I lifted the hood a little they were up to 170!), front of alternator is over 200! The engine itself is only at 160(by laser).
I have the revi with the cai! there is a lot of heat soak in this engine bay. My surface temps on the above items excluding the alternator, are actually lower on the track than the street.. As long as you are moving I dont think the charge temps are going to be a problem. Now stop and go stuff with the a/c on---we will see. May need some more shrouding and BOTH fans on at a lower temp.
install in October-possible track in november

jskup1 and I used The greedy Universal.
http://www.cardomain.com/item/GRE12004901
It cost a few bucks, but is worth it!
Good luck!

The part that screws in place of the stock oil filter location appears to be slightly too small, so I've been unable to complete the install.
I did a quick search and found what you bought, and what I bought:
http://www.directtuning.com/store/pc...m20-x-p15.aspx
http://www.directtuning.com/store/pc...m20-x-p15.aspx
They both list the specs as UNIV M20 X P1.5.
Anyone know what else might be different?
edit: here is yours on cardomain:

here's mine on cardomain:
http://www.cardomain.com/item/GRE12014901
mine has a higher part #, and they claim it fits the same oil filters... is there a trick to threading it? The issue I had with installing it onto the car was not limited to the car itself. I have the racing beat sandwich adapter, and that too refused to thread onto the relocation kit (bottom end).

There are 2 different Universal Kits for the Miata (Base) They both claim to be universal for Mazdas, but in fact are not. Jon actually had to call Greddy USA and they gave him the correct unit number.
The very likely hood for confusion is why I posted the link so that anyone interested in the kit would be ordering the correct unit. Sorry for the confusion, if I am the one who caused it.

nah, you didn't cause it. I ordered through my friend since he sells this stuff wholesale, so I get a much better price. but it looks like the dual mazda universal kit production has bitten me on the ***.

Yea everyone i called/contacted stated they were not caring the universal kit anymore?? So bought adapter and filter bracket off e bay. It has gauge ports. no lines or anything. looks trick. await delivery.
the only way i could use the rb plate and a universal kit was to order an adapter nipple(20x1.5) from mocal. got too involved.
Now my next step is to get the custom windshield washer bottle from Maxsport (it is part of their custom bottle setup--you can buy separately) which frees up a lot of firewall room. The mount oil filter and new bottle on firewall.
Finalized payment this week--glad i got in before the price increase!
I considered going to cam's for the install and,,, ummmm, "custom" err ,beta work---yall know but couldnt get time off from work. It is a 500mile drive for me.
So still going with my original plan to install myself.
questions /help please:
How much weight is added to the front of the car with this install?
How did all handle the maf install---cut the stock one off the airbox and use it?
has anyone considered adding a small pusher fan on the front part of one intercooler? Activated by a/w coolant temp and or manually? Maybe not needed?
I plan on monitoring charge temps--maybe from the manifold itself.
Yall are still running pre mix--right?
thanks in advance!

Any word on when the "Stage III" will be available and what kind of numbers and price tag to expect? The stage 2 is looking less apealing to me as I'd like 300whp if I'm going to dish out that kinda money.

Based on the numbers so far... the SII s/c is by default producing +96 HP (175 bs - 271 s/c). That is a 55% increase in HP. You would normally expect to receive 33-45% increase when you go FI. It is a totally different car with the s/c! I think for the money it is right on target, but that choice is only your to make.
We are not releasing any official numbers on when, where and how much the SIII kit will cost.
Unofficially....
Maybe +30 - 40 More HP(There is your 300+WHP)
Maybe +10 Torque
Maybe Flashed (No 3rd party EMS required)
Maybe Mid-Late December 07 Release
Unofficial....

Dan, Maybe you should just keep your comments to yourself until you are allowed to release official info. Even though I can see what you are trying to say without putting yourself and Pettit in a bad spot in case something unexpected happens, it seems like some people would rather attack you than let you help truly interested individuals. But Maybe I'm wrong.

I'm not trying to start a war with anyone and I'm not insinuating anything. It's just that little asinine comments by a lot of people are just starting to get old in these threads. Also, I think Dan knows a little bit more than people give him credit for or else Pettit wouldn't trust him to speak for them.

Yeah I would imagine that the stage 3 would make somewhere around 300whp. If they are able to provide a flash, that would save the costs of a Int-x. If it provided larger injectors and fuel pump it might drive the price up. It's not off par but it's a good chunk of change.

I know what you are saying Jon, but I'll take my chances! I speak the truth as I know it. My conscious is clear and if I am wrong or make a mistake... you know I a man enough to own it and publicly announce it so that the wrong info is not carried around as fact or truth.
I am not sure what was being said about the numbers I posted Ray?
From a recent dyno... those are the numbers I pulled from a the Dyno sheet. Is my Math wrong? JOn is also getting me his Dyno which is also within the corridor for which I based my numbers on. Naturally it is an average as everyone will have slightly different results. The numbers on Pettit's site are still a bit lower than what is being seen in the real world on the road. Not ridiculously low, but conservatively lower than what it out on the road. My car will Dyno this weekend and we'll see if my money is where my mouth is! (Let me clarify that these numbers apply to MT's. Not sure what AT's are achieving as of hard dyno info.)
Cam does not want to keep getting caught up in the "Semantics" Game, so he wishes for the stuff released to be factual. I am still attempting to look out for the Owner and the Customer. I do not want to say "NO COMMENT" to every question. I also do not wish to mislead or publish false info, so I will note with Maybe's so we cannot be slaughtered. If something is represented that "May" be wrong... A PM would be nice. I will make any corrections and/or credit the one who pointed it out. I'd like to keep it to that. Respect for one another. We all like each other. We all want better offerings. We all need a beer unless your sober like Pat... then you just need a tight hiney to grab! LOL

Ask I have always said--words by themselves are a bad form of communication. i think both posting here are cool--no probs. It just may just SOUND like they do.
a dyno was just posted on the other thread with a car that is running no engine management system other than oem. It has the torque curve and it pasts the 5252 rule.
take a look.
personnally i dont like dyno conversations. Multiple runs from the same car on the same day during tuning is great FOR THAT CAR. It MAY be similar for other cars but it also may be much different. it is something to focus on however. And i guess it does give some very general information,

I will be getting a few more Dyno Sheets tomorrow. I'll have them up as soon as I have em.
Also.... Anyone who has been watching the system may have noticed that the price just went up another $500 a few weeks ago.
Well, I have it that there are about 5 more units left from this last production run. I also have it that Pettit will let these last few units go at the original $4995.00 Price Tag. (Flash is NOT included)

hey.....farck the dyno sheets....
i just wanna smell the exhaust, listen to the whine, look at the fire and eat some burgers...
isnt that what we're doing this weekend???
correct me if im wrong!!
oh...and dabbling with a little bit of construction paper and a glue stick...
<stick is non-toxic and not for sniffing>

That's a rule-of-thumb that I just passed on to vicegrip and I plan on discussing such concepts Saturday night at Shinka's house. This rule works well assuming that the intake/exhaust systems do not become restrictions to airflow and that IATs are equal to ambient. The construction paper will help to use the dyno sheets more effectively but I need scissors and not glue stick because it won't get me high.![Lol2](https://www.rx8club.com/images/smilies/lol2.gif)
Actually, Pat, now that I think about it I won't need any paper either. I regular ruler/straightedge will do just fine.

Ray and I were discussing the nuances in pre-calculating output, and the finer points of calculations in general. I was tasked for my Torque estimate for stage III earlier as being a bit too low!
(There is NO bad blood... just sharing of information!)
I will make it clear for everyone that I am trying to speak in real world outputs... NOT SAE bullshit flywheel crap. While Ray is right, that knowing all the calculations for parasitic loss, etc and so on, can make me "look" more smarterer... I never, for a second, think that anyone is going to strap a motor on their skateboard and sit on top as they rip on down the road. Why should I say that the Stage II is putting out 316HP SAE or BHP or RHP so everyone needs to pull out their little calculators to dissect the equations? What everyone is attempting to figure is what is put on the blacktop. They Dynos speak to that regard. 10-20% drive shaft loss does not mean poo-poo when you say it is dropping X at the wheels. That is the real number. So I try to keep it simple, both for myself (I'm not the brightest guy and I hate math), and for other that are looking into this system. All the high-end fancy technical stuff can be provided if requested.
I also may need to say that it is my most humble opinion that what the 8 lacks is Torque, especially in the low end. Torque numbers, for me, are actually more powerful than the HP numbers. Never the less, most users look at the HP as the end all and the additional torque just a secondary bonus.
I am still waiting on some more dynos sheets to hang up, but I was way too busy to babysit today.
